@Saveen Thank you,but I guess you did not get my question.I want to create a sdk using Swagger codegen which creates an interface like above for every api calls made..I want to know about the command actually which for java is : java -jar swagger-codegen-cli-2.1.4.jar generate -i localhost:8080/v2/api-docs -l java -o retrofit/ -c config.json - rcde0
@Selvin And the question is what I asked. - rcde0

You can generate a Java Retrofit API client with RxJava enabled using the following command as an example:

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
-l java -i http://petstore.swagger.io/v2/swagger.json \
-c /var/tmp/retrofit2rx/java-petstore-retrofit2rx.json \
-o /var/tmp/retrofit2rx

and the JSON config file (/var/tmp/retrofit2rx/java-petstore-retrofit2rx.json) defines the following:

{
  "library": "retrofit2",
  "artifactId": "swagger-petstore-retrofit2-rx",
  "useRxJava": true,
  "hideGenerationTimestamp": true
}

You can then find the auto-generated code under the /var/tmp/retrofit2rx folder.

Please use the latest stable version of Swagger Codegen instead: https://github.com/swagger-api/swagger-codegen/releases, or pull the latest master of swagger-codegen to enjoy the enhancements and bug fixes.

To get a list of options for customizing the Java API client, please run the following command:

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar config-help -l java

UPDATE: On May 2018, about 50 top contributors and template creators of Swagger Codegen decided to fork Swagger Codegen to maintain a community-driven version called OpenAPI Generator. Please refer to the Q&A for more information.

I would recommend Swagger Gradle Codegen, Generates Kotlin code and Retrofit interfaces, with RxJava2 for async calls, Moshi for serialization and ThreeTenABP for Data management

For codegen you can use this for the JSON config file, is very similar that above response but I had to use useRxJava2 instead of useRxJava, like this: :

 {
    "library": "retrofit2",
    "artifactId": "swagger-petstore-retrofit2-rx",
    "useRxJava2": true,
    "hideGenerationTimestamp": true,
 }
